| Cycloaddition is a chemical reaction in which molecules containing double or triple bonds join together to form a ring-shaped structure. These reactions are important in organic chemistry because they allow complex molecules to be built efficiently. This video focuses on the most well-known type of cycloaddition: the Diels–Alder reaction. About the reaction |
The Diels–Alder reaction involves two molecules: an alkene with one double bond and a diene with two double bonds.
This reaction belongs to the class of pericyclic reactions. It proceeds through a special transition state in which the bonds are not yet fully single or fully double.
The reaction produces a ring-shaped molecule containing one double bond. In the process, two new carbon–carbon bonds are formed between the original molecules.
This is why the Diels–Alder reaction is so valuable: in a single step, it creates multiple carbon–carbon bonds, making it a powerful tool for building new molecules, from medicines to advanced materials.

The Diels–Alder reaction can also occur when the diene and the alkene carry different substituents — additional groups of atoms attached to their carbon frameworks.
A double bond consists of two components: a sigma (σ) bond and a pi (π) bond. The pi bond is formed by overlapping p orbitals — elongated regions of electron density shaped like a three-dimensional figure eight. The Diels–Alder reaction involves three double bonds, which means six p orbitals interact with each other.
